Incorrect return annotation in functions find() and find_all()

[Lemonade]

When I was coding in my IDE I noticed that I get an error here but code still works just fine:

subsections = html.find_all("div", class_="subSection detailBox")
    for subsection in subsections:
        subsection_title: str = subsection.find("div", class_="subSectionTitle").text.strip()

        link_objects = subsection.find_all("a", class_="modalContentLink")
        name_objects = subsection.find_all("b")
        links: list[str] = [obj.get("href") for obj in link_objects]
        names: list[str] = [obj.text for obj in name_objects if obj.text != ""]

Unresolved attribute reference 'find' for class 'PageElement'
Unresolved attribute reference 'find_all' for class 'PageElement'

The reason why is because return annotation in these functions are Optional[PageElement] and ResultSet[PageElement] respectively.

I ran print(isinstance(subsection, bs4.Tag)) and it returned True.
To solve this issue I simply changed [PageElement] to [Tag] in bs4 element.py file
